As a professional plant enthusiast, I have found that watering calathea plants can be a bit tricky. Here are some watering tips that have worked well for me:

1. Water when the top inch of soil is dry

Calathea plants prefer moist soil but can be sensitive to overwatering. To avoid this, it’s important to wait until the top inch of soil is dry before watering. Stick your finger into the soil to check for moisture levels.

2. Use room temperature or lukewarm water

Calathea plants are sensitive to temperature changes, so it’s best to use room temperature or lukewarm water when watering. Cold water can shock the roots and cause damage.

3. Use filtered water or rainwater

Calathea plants are sensitive to chemicals found in tap water, such as chlorine and fluoride. To avoid any potential issues, it’s best to use filtered water or rainwater when watering your calathea plant.

4. Water less in winter

During the winter months, calathea plants go into a period of dormancy and require less water. It’s important to reduce watering during this time to avoid overwatering and root rot.

5. Don’t let the plant sit in water

Calathea plants don’t like to sit in water, so it’s important to ensure that the pot has proper drainage. If excess water accumulates in the saucer, be sure to pour it out to prevent the roots from sitting in water.

By following these watering tips, you can help ensure that your calathea plant stays healthy and happy.

Humidity Needs of Calathea Plants

Calathea plants are native to tropical areas and require high levels of humidity to thrive. As a result, it’s important to keep the air around your calathea plant moist.

I find that misting the leaves of my calathea plant with water is a great way to increase humidity levels. I usually mist my plant once a day, especially during the dry winter months. You can also use a humidifier to keep the air around your plant moist.

In addition to misting or using a humidifier, you can also place a tray of water near your calathea plant. As the water evaporates, it will create a humid environment for your plant.

It’s important to note that calathea plants are sensitive to changes in humidity levels. If the air around your plant becomes too dry, the leaves may start to curl or brown at the edges. On the other hand, if the air is too humid, your plant may become susceptible to fungal diseases.

In summary, keeping the humidity levels high is crucial for the health of your calathea plant. Regular misting, using a humidifier, and placing a tray of water nearby are all effective ways to increase humidity levels and keep your plant happy and healthy.

Temperature Requirements for Calathea Plants

Calathea plants are native to tropical regions, so they require warm and humid conditions to thrive. As a general rule, they prefer temperatures between 65-80°F (18-27°C). In temperatures lower than 60°F (15°C), Calathea plants experience stress and may suffer from leaf damage.

However, it’s important to note that different species of Calathea may have varying temperature requirements. For example, Calathea orbifolia prefers cooler temperatures between 60-75°F (15-24°C), while Calathea zebrina prefers warmer temperatures between 70-85°F (21-29°C).

To ensure that your Calathea plant is in the optimal temperature range, it’s important to avoid placing it near drafts, air conditioning units, or heating vents. Additionally, if you live in a dry climate, you may need to use a humidifier to maintain the necessary level of humidity for your Calathea plant.

In summary, Calathea plants require warm and humid conditions to thrive, with temperatures between 65-80°F (18-27°C) being ideal. Different species may have varying temperature preferences, so it’s important to research the specific requirements of your Calathea plant.

Fertilising Calathea Plants for Optimal Health

Calathea plants require regular fertilisation to maintain their optimal health. I typically fertilise my Calathea plants once a month during the growing season, which is usually from spring to early fall. During the winter months, I reduce the frequency of fertilisation to once every two to three months.

When selecting a fertiliser for Calathea plants, I recommend choosing a balanced, water-soluble fertiliser with equal amounts of nitrogen, phosphorus, and potassium. A balanced fertiliser will provide all the necessary nutrients that Calathea plants need to thrive.

I dilute the fertiliser to half the recommended strength before applying it to my Calathea plants. Overfertilising can damage the plant’s roots and leaves, so it’s essential to follow the instructions on the fertiliser package carefully.

In addition to using a balanced fertiliser, I also recommend using a fertiliser that contains micronutrients such as iron, magnesium, and calcium. These micronutrients are essential for the plant’s growth and development and can help prevent nutrient deficiencies.

Overall, fertilising Calathea plants regularly with a balanced, water-soluble fertiliser and micronutrients can help maintain their optimal health and keep them looking vibrant and beautiful.

Toxicity Concerns with Calathea Plants

Calathea plants are known for their beautiful foliage and are a popular choice for indoor gardening. However, it is important to note that these plants can be toxic to pets and humans if ingested.

As a professional gardener, I always advise my clients to keep their calathea plants out of reach of children and pets. The leaves of the calathea plant contain oxalates, which can cause irritation and swelling in the mouth and throat if ingested.

In addition to the risk of ingestion, handling the plant can also cause skin irritation in some individuals. It is recommended to wear gloves when handling a calathea plant to avoid any potential skin reactions.

If you suspect that your pet has ingested a calathea plant, it is important to contact your veterinarian immediately. Symptoms of ingestion can include vomiting, diarrhea, and difficulty breathing.

In summary, while calathea plants are a beautiful addition to any indoor garden, it is important to be aware of the potential toxicity risks associated with these plants. Keep them out of reach of children and pets, wear gloves when handling, and seek medical attention if ingestion is suspected.
